Representing a venue

Abstract

Techniques for storing information representing a venue are described. A system can represent a venue as a set of one or more nested data objects. A top layer of the nested data objects can include a venue data object that stores coarse information of the venue, including an identifier, a name, and a geometry of the venue. A second layer of data objects that are nested in the venue data object can include one or more building data objects that have finer granularity than the venue data object. Each building data object can store information on a building located at the venue, including name of the building, address of the building, and a geometry of the building. Additional layers of data objects representing further details of each building.
